No assembly required, just stretch and install.

Wrong size and it came with a hole in it. The packaging was HORRIBLE!! Will not ever buy again.

Like the fact that it's metal

I love this box spring! I got the 4” for my queen bed and it’s much quieter than the bunkie board I was using before. As a matter of fact, it doesn’t make a sound. My bed is much for stable and comfortable because of it. I will be replacing my son’ bunkie board with a Zinus box spring within the next few weeks. Assembly (or lack thereof) was also a breeze - simply unfold and place the cover on!

We bought our second mattress because we upgraded from a queen to a king. This time we added the box spring to our purchase and it’s one of the best decisions we’ve ever made. This mattress is comfortable, the box spring is heavy duty, and we are going to be Zinus customers for a long time. We could not be happier.

Great product at a great price. I now have two of them, one in cal king and one in queen. Both are performing well. Note: When you set one of these up, make sure there is another person around to help with the unpack and the unfold. And follow the instructions!

I had already purchased the 13" Night Therapy Deluxe Euro Box Top Spring Mattress and needed a new Foundation. The video that showed the Night Therapy Bi-Fold Box Spring Folding Foundation-Full showed it being placed on the existing full size bed frame. When I received this bi-fold foundation, it did not fit my existing frame. I checked and found the Night Therapy Smart Base Steel Bed Framed Foundation-full, for $100 less. I now have my new bed setting on the floor because I ordered the wrong foundation. In that respect, I am not satisfied fully with this purchase. Maybe this will help someone else purchase the correct items.

The craziest thing of this BiFold Box Sping is the Assembly process. It took me less than 5 minutes to break the box seal, unpack each of the Boxes, Lay them on the wooden slats of my Bed and unfold them to zip the clothing cover. And I'm pretty sure, It will take the same amount of time to pack them when moving as well. Don't hesitate. Just get this Box Spring and leave everything else to Zinus.

Ours did not come with the cover on. It tore as we tried. Both the way in the picture and any possible combination. We have done many other types of furniture assembly; this one had us stumped. Called manufacturer customer service and they were no help. Almost every YouTube video we found showed the cover on it. Will see how this works once in use.

So far, we are very pleased with our mattress. The box springs were genius- theycame right out of the box and assembled immediately. This was only our 2nd night of sleeping on our mattress, but they’ve been wonderful so far. The chemical smell is a bit offputting in the beginning, but it’s alrwdy starting to fade. I’ve been telling everyone about our mattress! Can’t wait to keep sleeping comfortably. and at 35 weeks pregnant, that can be difficult!
